X-Ray Reflection Study on Block Copolymer Langmuir Films — •Volker Schön and Patrick Huber — Saarland University, 66123 Saarbrücken, Germany
We present X-ray measurements on Langmuir films of amphiphilic block copolymers of varibale length at various surface pressures corresponding to different phases in their compression isotherms.
The measurements were taken on a home made butterfly X-ray reflectometer with an accessibility of up to 9 orders of magnitude in reflected intensity while the films were prepared and controlled in a Langmuir trough.
The obtained reflectivities give hints to distinct conformational changes within the films investigated.
